# MySQL/MariaDB - Compatibility Research
|
|
|
|
## Latest Version & Changes
|
|
**MySQL**: Version 8.0 (stable, widely adopted)
|
|
**MariaDB**: Version 11.4 LTS (recommended as of June 2025)
|
|
|
|
### Market Trends (2025)
|
|
- **Shift**: MariaDB now powers more WordPress sites than MySQL (as of March 2025)
|
|
- **Performance**: MariaDB 13-36% faster than MySQL 8.0
|
|
- **Adoption**: Growing preference for MariaDB in new projects
|
|
|
|
## Compatibility Analysis
|
|
- **Drop-in Replacement**: MariaDB 10.6+ limited compatibility with MySQL 5.7
|
|
- **MySQL 8.0 vs MariaDB**: Significant differences, not directly compatible
|
|
- **Connectors**: All MySQL connectors work with MariaDB
|
|
- **Binary Compatibility**: MariaDB data files generally compatible
|
|
|
|
## Known Issues & Problems
|
|
- **Replication**: MariaDB <10.6.21 cannot replicate from MySQL 8.0
|
|
- **GTIDs**: Different implementations between systems
|
|
- **Feature Differences**: Growing divergence in advanced features
|
|
|
|
## Best Practices & Recommendations
|
|
### For New Projects (2025)
|
|
- **Recommended**: MariaDB 11.4 LTS (better performance, features)
|
|
- **Alternative**: MySQL 8.0 (enterprise-grade, wide support)
|
|
|
|
### Migration Considerations
|
|
- **MySQL to MariaDB**: Generally straightforward
|
|
- **MariaDB to MySQL**: More complex due to feature differences
|
|
- **Version Strategy**: Avoid MariaDB <10.6 (EOL status)
|
|
|
|
### Production Recommendations
|
|
- **Primary Choice**: MariaDB 11.4 LTS
|
|
- **Fallback**: MySQL 8.0 for enterprise requirements
|
|
- **Compatibility**: Plan for potential differences in advanced features
